E70' all whom t may concern:

Be it known that lt, Vieron L. Roninzrrson, a citizen of the United States, residing at herzberg, in the county oit Madison and State oit Idaho, have invented new and usefnl improvements in iutoinobildritricators, of which the following is a specii'ication.

rfhis invention. relates to automobile extricators the object in view being to provide portable means, capable of being carried in one oit the compartments oi' a motor vehicle, whereby a niotor vehicle is adapted to extricate itseliI trein a mired position or difliciilt place under its own power and without any extraneous devices other than the extricatingrl apparatus carried thereby.

'ilhe inain featureot` the present invention resides in the use, in combination with a iiexible chain, ot novel anchoring means for securing one end of said chain in fixed relation to the road surface, said anchoring ineens embodying two normally coupled or interloclied ineinbers capable olf automatically separating one 'from the other when the. motor vehicle reaches a predetermined point in its path oit travel.

A further object in View is to provide an anchoring device, as a whole, of such construction that the anchor cxtricated from the road surface automatically when the 'vehicle reaches a predetermined point in its path of travel.

iNith the above and other objects in View, the .invention consists in the novel construction7 combination and arrangement ot parte, herein fully described, illustrated and claimed.

ln the aceompaiiying1 draWings:-

Figure l is a side elevation showing the manner in which the extricator is used.

Fig. 2 is a plan view oi the extricator detached 'from the vehicle.

Fig. 3 is a detail perspective view of the main body oi the anchor.

Fig. is a similar View oi." the coupling inernber, and

liig. 5 is a detail View showing the relation et the ancl'ioring member and coupling ineinber to each other.

7il`he ertricatoi contemplated in this iiirention comprises a base plate or anchoring plate l ot any suitable width and length,

the same being; provided at its forward end or that end which faces the vehicle with a large spur or prong 2 adapted to be driven into the road surface, the prong 2 being inclined with relation to the body et' the plate at an angle of approximately 450, more or less. Adjacent to its rear end the anchoring member or base plate i is formed with transversely elongated holes 3 to receive Hat spikes Il having heads 5 adapting them to be driven into the ground through holes 3, the holes loeingT inclined as shown so that the spikes Ll may be driven into the road surlace at an inclination in the same direction as the toe spur or prong 2. The plate l is VFurther provided at its opposite rear corners with lugs or stops 5, the purpose otl which will appear.

6 designates a coupling; plate of any suitable width and length, having at the rear end thereof a broad hook 7 the length of which is slightly less than the distance between the lugs or stops 5. The hook 7 is adapted to engage the rear edge of the anchor plate l as best shown in Fig. 5. At 'its forward end, the plate (S is provided at the opposite corners thereof with hooks 8 which are adapted to engage the terminal eyes 0 of an extension chain l0 embodying the longitudinal side members 11 and the cross chains 12, each of the cross chains 12 being;1 Fixedly connected at one end to one of the longitudinal members or chains and beingl provided at its opposite ends with a hook or snap 13 by means o'l which said ends of the cross chains may be detached from the adjacent side chain or longitudinal member.

The extension chain referred to is adapted to be connected by hooks and eyes as shown at 14 to an ordinary antiskid chain designated generally at 15. At its rear end, the chain l5 has connected thereto a short chain i6 provided at one oiboth ends with snap hooks 17. Illhe chain 16 is thus detachably connected at one or both ends to the rear end of the antisliid chain and passes through a flexible tube '18 of rubber or like materiel, enablingr the chain to be attached to one oit the spokes oi the rear wheel of a motor car, the rubber tube preventing `chafinp; and marring the finish of the Spoke which it engages and also the telly adjulcent thereto.

In the use ot the extricatino; apparatus hereinabove described, two sets of chains and anchors are employed, one for attachmeot eecli oi@ tlie cliiifiog wheels of tlie ileliiicler ,llie snclioiiiig pleitos l are ifst mly siiclioiecl to tlie ioscl siii-lace by tlie ineens alesciiloecl escl tlieii the coupling; plates 6 sie associated with the anche? plates iii the cosmici illiistiete'cl. lllie extension chains site then compl-eel to tlie siitislicl on'tlieii llooliecl connection with toe eiichoi plstes., This serves 'to pull uowoiclly on the spikes l, clisloclging the seme from their positions, and immediately thereafter the hooks 'Z' disengege themselves from the on- Choi1 plates l. The vehicle may continue to a suitable position solo; tlie oiiclioi" -gletes l moy then be i'ecovei'ed and placed in the Ve-v liicle. v By boeking; the vehicle, the cli-eins may be mrc/ouml item the driving; Wheels thereof sini removed soil also placed io the veliicle.

lt is of? course to oe unclerstoocl 'that tlie seme apparatus enables tlie vehicle to extricste itself io e ieeiweil cli'ectioii by simply extending the clieios in tlie opposite zliieotioii oiii tlie ieee driving; Wheels to Wliicli they sie ift-estese@ eiifl locating tlie coches ing ind coupling ineens sccofcliogly.
